libass (0.17.2)
* Fix rendering of \h in certain cases
* Fix a minor memory leak in the CoreText and DirectWrite font provider
* Fix wrong ASS_Image dimensions for huge BorderStyle=4 backgrounds
potentially leading to out of bound reads by API users
* Improve quality of animated rectangular clips

* Full-Unicode cmaps are now always preferred
* Improve font selection compatibility in the DirectWrite font provider
* Improved documentation
* Color mangling notes in ass_types.h were updated for tone mapping and HDR video
* Guidelines for producing portable ASS files can now be found in our wiki
* Updating selective overrides now forces a cache clear to avoid issues with outdated caches
* Frame and storage resolutions are now limited to what a single ASS_Image can represent
* make check now runs checkasm if assembly is enabled
* CoreText can now be used on Mac OS X 10.5
* Meson/muon is now offered as a secondary build system bringing back first-party MSVC support
Note however it is not at feature parity with autotools in all cases
* aarch64: add optimized assembly routines covering the same set as on x86;
they work on both little and big endian systems
* x86: add SSSE3 versions of some assembly routines to help CPUs without AVX2
* x86: it is now possible to build binaries with optimized assembly and SHSTK support
* Improve VSFilter compatibility:
* Trailing spaces are no longer trimmed from style and
event string fields (this does not affect Text)
* All BiDi paragraph separators now delimit BiDi runs
* Fix treatment of font weights < 10
* Match GDI's faux italic slant
* Employ faux italics and faux bolding in the same cases as GDI
* Better match font selection with regard to italic and weight
* Treat empty Style name as "Default"
* Various drawing fixes
* Reject drawings not starting with a valid m command or invalid m followed by valid n
* Drop coordinates following invalid commands rather than appending them to the prior command
* Ignore p commands without enough preceding nodes
* Partially fix s and p commands used outside of a properly closed b-spline sequence
libass: updated to 0.17.1 libass (0.17.1) * Fix buffer overread if soft-wrapping occurred and ASS_FEATURE_WHOLE_TEXT_LAYOUT was enabled via API or due to Encoding -1 (bug introduced in 0.16.0) * x86: detect GNU Hurd and configure NASM appropriately
libass: updated to 0.17.0

* Add ASS_FEATURE_WRAP_UNICODE to allow automatic linebreaks in accordance
with the Unicode line breaking algorithm instead of ASS' much stricter
breaking rules. For the feature to be available at runtime, libass must be
linked against the new optional dependency libunibreak.
* Improve VSFilter compatibility:
* Fix premature truncation of animated alphas (was a 0.15.0 regression)
* Fix handling of small delay parameters for legacy SSA Effects

libass: updated to 0.16.0
libass (0.16.0)
* Fix missing `-framework` options in libass.pc on macOS
* Fix missing GDI or DirectWrite options in libass.pc on Win32
* Fix crashes with fonts missing Postscript names and without one
being synthesised by the font provider
* Fix crashes on negative fontsizes and some overflows
* Fix a rare memory leak introduced in 0.13.0
* Fix minimum dependency versions in configure and our pc-file
* Fix our public headers for use with GCC versions between 3.1.0 and 4.5.0
(was a regression introduced in 0.15.0)
* x86: Fix potential buffer over-read by 16 bytes with AVX2 assembly
when large tiles are not enabled (the default)
* x86: Fix PIC flags not being interpreted by the assembler, breaking the
asm-enabled build setup on NetBSD and OpenBSD. On 32-bit x86, if the toolchain
requires PIC objects and relies on compiler defaults to get PIC implicitly,
you need to pass `--with-pic` to configure to ensure NASM always produces
PIC objects
* x86: Fix AVX support not being detected on non-Intel CPUs and some VMs
* x86: Fix CPUID being used on CPUs not supporting the instruction (<= i486)
and the way it is used for CPUs with less than 7 CPUID-leafs
which could lead to crashes due to illegal instructions
* MS Windows-only issue: Fix crashes with FreeType >= 2.11.1 on Win32
when rendering strikethrough or underline
* Improve `\iclip` quality
* Improve quality of very small outlines
* Switch to wyhash for much better cache performance
* Propagate ZWJ/ZWNJ effects across glyph run boundaries
* Do not depend on compiler-specific defines to actually use built assembly
* Expand documentation and fix mistakes in it
* configure now errors out if an explicitly requested feature is unavailable
* MS Windows-only issue: ease linking against static/shared GNU FriBidi
* Add ASS_FEATURE_WHOLE_TEXT_LAYOUT to apply bidi, shaping and \fay
to the entire unsplit event text. The non-portable `Encoding=-1` mode
always behaves as if the feature were enabled
* MS Windows-only issue: add support for arbitrary Unicode paths;
see documentation of related functions for details
* Improve VSFilter compatibility
* Do not treat format lines using `Actor` in place of `Name`
as custom format lines. The former is used by VSFilter itself,
the latter by Aegisub
* Run bidi and shaping on each glyph run separately by default
* Match VSFilter's \fsp effects on bidi and shaping
* Match VSFilter's \fay behaviour
* Support non-Unicode font cmaps when Win32 API or iconv
is available and can convert to the relevant encoding
* Treat empty clip outlines as if everything was outside the clip
not inside (was a 0.14.0 regression)
* Parse integer parameters of override tags more like VSFilter
multimedia: Replace RMD160 checksums with BLAKE2s checksums All checksums have been double-checked against existing RMD160 and SHA512 hashes The following distfiles could not be fetched (for legal reasons?): ./multimedia/adobe-flash-player/distinfo adobe-flash-player-32.0.0.465/flash_player_npapi_linux.i386.tar.gz ./multimedia/adobe-flash-player/distinfo adobe-flash-player-32.0.0.465/flash_player_npapi_linux.x86_64.tar.gz ./multimedia/libdvdcss/distinfo libdvdcss-1.4.3.tar.bz2
multimedia: Remove SHA1 hashes for distfiles
libass: updated to 0.15.2 Release 0.15.2 This is a bug fix release without API or ABI changes, mainly to fix more known 0.15.0 and 0.15.1 regressions. But as a bonus, it is now possible to build the DirectWrite system font provider for Microsoft’s Universal Windows Platform (UWP). Two known minor 0.15.x DirectWrite system font regressions remain: when a font is attached/memory-loaded but a different (non-attached) style of the same font is used by the subtitles (only the attached style[s] will be used; this also affects Core Text since 0.13.0 but not Fontconfig); in the unlikely case that the full name of a system font equals the family name of another system font (only the family name matches will be found). Also please note that our IRC channel #libass has moved from freenode.net to Libera.Chat, and all presence on freenode.net has been fully retired. Changes: Fix some known 0.15.x regressions: Fix Core Text font fallback failing on some fonts with multiple names Fix DirectWrite failing to look up any but the first loaded variant of system fonts Fix some format string bugs, which could lead to garbled log messages or on some platforms crashes Fix ass_set_fonts_dir failing to load long paths Better handling of control characters that have no associated font glyphs DirectWrite: font lookup is now closer to VSFilter DirectWrite: this font provider can now be built for UWP
libass: updated to 0.15.1 Release 0.15.1 This is purely a bug fix and polish release, with no significant API or ABI changes. The only API change is that ass_add_font is now declared to accept const char *. Previously it took only char *, but const has worked in practice since the very first standalone libass release. Fix currently known 0.15.0 regressions: Fix crashing on some ASS files with embedded fonts Fix total font fallback failure with some fonts on Core Text Fix embedded and memory fonts not actually being used unless ass_set_fonts was called after they have been added Fix events assuming the largest xbord-value of a preceding event of the same frame during collision handling Fix \fscx0 and \fscy0 making more text disappear than they should Fix shift in vertical positioning of some right-to-left events with \an4-6, \pos, \move or Scroll effects Fix imprecise output for \be with huge argument Fix the --enable-large-tiles configure switch doing nothing Fix output of ASM-enabled builds deviating from non-ASM builds Fix ASM-builds on Haiku and 32-bit *BSDs Overhaul x86 assembly for better performance and to allow ASM-enabled PIC-builds on 32-bit Reduce temporary allocation in rendering DirectWrite: request fonts on demand for better performance and improved compatibility with external on-demand font activation Log libass version numbers upon renderer startup Accept pointers to const as arguments to ass_add_font Improve VSFilter compatibility: Disregard zero area events in collision handling Do not apply \fsp to vector drawings Fix bug preventing cutting out glyphs from border & shadow with abnormal \fad values (or causing aliasing artifacts in some cases with normal values)
libass: updated to 0.15.0 Release 0.15.0 Boo! Three long years in the making due to large internal changes, this long-awaited release brings bug fixes, speed, and a new mechanism for opting into VSFilter-incompatible features: Fix backwards/VSFilter-incompatible font sizes with FreeType 2.10+ Improve speed via better caching Require HarfBuzz unconditionally to ensure good shaping for complex scripts ass_set_use_margins(true) now simply places text on the whole screen instead of attempting to tie it to video positioning (set by the margin values) and failing in various ways when margins are used to implement pan & scan in a video player Add ass_track_set_feature() & catch-all ASS_FEATURE_INCOMPATIBLE_EXTENSIONS Add ASS_FEATURE_BIDI_BRACKETS to enable Unicode 6.3+ bracket matching when applying the Unicode Bidirectional Algorithm (incompatible with VSFilter; requires libass built with FriBidi 1.0+) Fix stack overflow on deeply nested \t tags Fix positioning of events with leading line breaks Fix small but nonzero \bord becoming \bord0 (regression in 0.14.0) Measure BorderStyle=4 box padding from glyph border, not from glyph fill Scale everything from script resolution if storage size is not set (including borders and shadows regardless of ScaledBorderAndShadow) Fix the default aspect ratio calculation when neither ass_set_pixel_aspect() nor ass_set_aspect_ratio() is called Multiple fixes for karaoke override tags Handle memory allocation failures better: avoid some crashes and produce images closer to truth Avoid some integer overflows Add internal infrastructure for regression testing Improve VSFilter compatibility: - Treat invalid nested \t tags like VSFilter - Make \t(T,T,...) at time exactly T use the post-transition values - Make lines stack more like they do in VSFilter - Default ScaledBorderAndShadow to 0 (like VSFilter), except for subtitles that were produced by old FFmpeg/Libav - Make shadow positioning with 3D transforms match VSFilter’s - Cut out glyphs from border & shadow in all the same cases as VSFilter - Match VSFilter on animated color tags with negative acceleration - Fix parsing of some files that VSFilter accepts but libass didn’t by ignoring leading whitespace in each line of an ASS file or CodecPrivate - Improve font selection with CoreText - Stop faux-bolding fonts that are too bold to get faux bold in VSFilter - Ignore leading/trailing spaces when calculating height of nonblank lines - Match VSFilter on \fade with large alpha value arguments - Stop splitting bitmaps on font substitution - Multiple fixes for Banner and Scroll effects - Multiple fixes for karaoke override tags
libass: updated to 0.14.0 libass (0.14.0) * Brand new, faster and better outline stroker (replaces FreeType stroker) * Remove option to use the FreeType rasterizer * Fix spots of missing border around self-intersecting shapes * Switch from Yasm to NASM for building hand-written assembler code * Support Core Text font provider on Mac OS X 10.6 and 10.7 * Clear font cache in ass_set_fonts(). This fixes potentially incorrect font choices and an occasional crash if this function is called midway through rendering a file.
Release 0.13.7 Fix invalid memory accesses with BorderStyle=4 Fix change detection bug on frame resizes Fix cache bugs with border size Reduce precision of border width in font outline caching Don't treat :;<=>? as hexadecimal digits in color headers Fix parsing of unusual Alignment values in ASS style definitions Fix potential truncation in timestamp parsing Treat negative PlayResX/PlayResY like VSFilter Fixes to parsing of embedded fonts Remove arbitrary bitmap limit (fixes issues with subtitle rendering at 4K) Allow using shadow offset to adjust size of background with BorderStyle=4 Fix TrueType/OpenType font collection handling with the DirectWrite backend
libass: update to 0.13.4
changes from 0.13.1 to 0.13.4
Bug fixes found with fuzzing
Fix memory reallocation in the shaper. (CVE-2016-7972)
Fix two small memory leaks in the parser and test program.
Fix illegal read in Gaussian blur coefficient calculations. (CVE-2016-7970)
Fix mode 0/3 line wrapping equalization in specific cases which could result in illegal reads while laying out and shaping text. (CVE-2016-7969)
Improve compatibility/portablility of build system, should fix e.g. compilation on Solaris.
Fix memory leak in DirectWrite font provider.
Fix the rasterizer when rendering some large outlines.
Remove hack that forced RTL base direction depending on font encoding.
Greatly improve the internal caches with refcounting and gradual clearing.
Add ass_set_check_readorder() API function to disable use of the ReadOrder field for duplicate checking in ass_process_chunk().
ass_step_sub(track, now, 0) now finds the start of the subtitle at now.
Bug fixes:
Fix an issue with the new duplicate checking, which could lead to missing subtitles after seeking.
Fix a crash with Core Text under specific circumstances.
Release 0.13.1: Much faster duplicate event check in ass_process_chunk. This can bring a large speedup for embedded subtitles with lots of events. To make this possible, it is now forbidden to combine calls to ass_process_chunk with any other method of manipulating the event list, namely, manual manipulation and calls to ass_process_data, ass_read_memory and ass_read_file. Interpret negative timestamp components as actual negative numbers. This change increases compatibility with VSFilter. Font matching changes for VSFilter compatibility Look up fonts that contain PostScript outlines by their PostScript name instead of their full names. Family names continue to be used for all fonts. Keep spaces in font names Drop support for Fontconfig < 2.10.92 to ensure correct font matching Bug fixes Fix building the assembler code for the x32 ABI Fix static linking against libass through pkg-config when libass uses libiconv Fix some small memory leaks, potential crashes and bad data uses
